N. PEIERS, Pham NITED STATES raient PATENT JOHN F. BEHLMFR, OF NEW YORK, N. Y.'

SPECIFICATION forming part of Letters Patent No. 357,696, dated February 15, 188'7.

Application filed May 8. 1886.

To LZZ whom it may concern:

Beit known that I, JOHN F. BEHLMER, of the city and county of New York, in the State of New York, have invented anew and useful Improvement in Carbonic- Acid-Gas Generators, of which the following is a specieation.

My invention is applicable to generators wherein marbledust or other substance is subjected to the action of acid in order to generate carbonicacid gas; and the invention relates to that class of' generators which comprise an acidreceptacle mounted upon. trunnions or journals, so tliatit is capable of turning` in order to pour from it the required quantity of acidy into the generator.

The invention will hereinafter be particularly described; and it consists in novel combinationsY of parts, which are pointed out in the claims. y

In the accompanying drawings, Figure 1 represents an elevation of a portion of a gen erator-vessel and a longitudinal section of an acid attachment surmounting the same and embodying my invention. Fig. 2 is an end View of the generator-vessel and a transverse section of the acid attachment upon the plane of the dotted lnexx','Fig. l; and Fig. 3 is an end View looking from the left hand of Fig. l, a handle which is upon the journal of the acid-receptacle being removed.

Similar letters of reference designate corresponding parts in the several figures.

A designates a generator-vessel,'which is of the ordinary or any suitable character, and to which, considered alone, my invention does not relate. p

Surmounting the generat0r-vessel A is a casing, B, which may be made of metal and which, as here shown, is of barrel-like or drumlike form and closed at, the ends by heads B. This upper casing, B, communicates with the generator-vessel A by a throat or passage, C, and it has at the top opposite the throat or passage C a corresponding opening, b, which is closed by a cap or cover, b. Within the casing B is the acid-receptacle D, which is, as

, here shown, of barrellike form, and which has at the top an inletppening, d. It is my intention to make the acid-receptacle D of glass, and it has at opposite ends studs or projec- Serial No. 201,624. (No model.)

tions d', -to which may be applied, by screwthreads or otherwise, the journals d2, on which the vessel D is pivoted. These journals d2 may be fitted, one of them to a closed bearing, da, atone end of the casing B, andthe other of them to a stufiing-box, d4, at the opposite end of the casing B, and through which that journal is prolonged, so as to receive a handle or haud-wheel, d5, for turning it. M

From this description it will be seen that the acid-receptacle D is journaled at opposite ends, so that itv may turn readily in a plane transverse to the length of the casing B. When the acid-receptacle is turned to the position shown, its opening d is immediately below the opening b in the top of the casing B, and by removing the cap b acid in suitable quantity may be introduced into the receptacle D. The receptacle D may at the proper time be turned upon its axis more or less, in order to pour through the opening d a desired quantity of acid, and the quantity so discharged may be gaged or regulated by means of a notched Wheel, e, upon-one of the journals d, with which engages a pawl ordetent, e', as best shown in Fig. 3. This locking and regulating device not only serves to prevent the accidental turning of the acid-receptacle D, but by it also the extent of turning the receptacle, and consequently the amount of acid poured therefrom through the opening d, may be gaged or regulated.

In order to properly control the acid which is poured out of the receptacle D into the throat C and to prevent it from coming in contact with the metal casing, I employ a shield or guard, E, which I also intend to make of glass, and which rests upon the bottom of the interior of the casing B and has a funnel-like mouth or neck, e2, projecting downward into the throat or passage C. This shield or guard E is prolonged upward at the ends near to the journals e? of the acid-receptacle D, and is carried upward at the sides of the receptacle D, as shown in Fig. 2, so as to shield or guard the opening d. rlhe acid-receptacle D is intended to be turned in the direction indicated by the arrow in Fig. 2, and on the side toward which the opening d is carried in turning the receptacle the shield E is prolonged upward nearly to the top of the recep- IOO taele D, as shown in Fig. 2, and also by the dotted and full lines in Fig. l. Consequently any acid which may tend to slop overor pour out of the receptacle when it is nearly full is prevented by this upward extension of the shield or guard E Yfrom slopping against the interior ofthe metal easing l5, and by the construction of this shield or guard the acid is all directed to the central outlctneek or funnelmouth e2.

ln order to afford a free space around the shield or guard E and between it and the interior of the casing B, so that all parts of the interior of the casing shall receive the same pressure that is within the generator, I have represented the casing B as provided with projections If from 'its interior surface at the lower portion thereof'. These projections may be made in the form of semieircular ribs or flanges, and on them the shield or guard E rests and is supported.

This apparatus is very desirable, because the parts with which the acid comes in contact may be made ol glass, and because there are no valves which may get out of order and leak.

That I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, with a generator-vessel andan upper casing communicating therewith bya throat, of 4an acid-receptacle having an opening in its top and journaledin the easing, and a shield 0r guard within the casing partly surrounding the acid-receptacle, and having a funnel outlet or neck extending downward into the throat between the upper casing and the generator-vessel, substantially as herein described.

2. The combination, with the generator-vessel and the upper easing, B, communicating therewith by a throat, C, and having projections on the lower portion of its interior, of the shield or guard E, resting on the bottom of the casing and provided with the outlet funnel or neel; e, and the acid-receptacle journaled in the easing and turning within vthe shield or guard, substantially as herei described. x
